The roles of Lisandro Martinez and Raphael Varane are really needed in this fight. Lisandro Martinez has hard work like a gladiator on defense, strong aggression, as well as tackling that is right on target, making it difficult for opposing players to pass. Meanwhile, Raphael Varane is more for defensive awareness and also for dealing with aerial balls which will often be longpassed by Barcelona players. So I hope these two players can defend Manchester United in the match against Barcelona later and hopefully won't be absent due to unwanted problems.
Sadly for Manchester United Lisandro Martinez will not be available for the first leg because he will serve his one match ban after picking up his fifth yellow card again Real Soceidad. He will be a big miss but united has other center backs like Maguire and Lindelof. I predict Lindelof will start in his place if he is fit or we could see Luke Shaw at the center back after his excellent performance when he was deployed there. Maguire could also be another option but I doubt he can be trusted in this match by Ten Hag. Overall Martinez will be a big Miss in the match
